HEATING-STOVE.

The Schedule referred to in these Letters Patent and making art of the same To all whom it may concern:

Be it known that I, DAVID L. Srrnns, of the city of Rochester, in the county of Monroe and State of New York, have invented a, certain new and useful Improvement in. Stoves, of which the following is a specification.

Nature of Invention.

in the fire-chamber, for distributing the air to support the combustion.

General Description.

In the drawings- Figure 1 is a sectional perspective view.

Figures 2 and 3, cross-sections, respectively, in the planes of lines :c x and y y, fig. 1.

A isthe main cylinder-of the stove, shown in the drawing as adapted to the burning of wood.

B B are a series of pipes or tubes extending upward from the main cylinder, and opening into. a chamber, 0, in the top of the stove.

D is a reverse jacket, opening downward from chamber 0, and extending to the top of the main cylinder, to which it joins with a division between.

E is an interior cylinder, opening from the firechamber, and ext-ending up through the jacketspace,-and opening above the chamber 6, into smokespace G. A passage, 1), is left between jacket-space D and cylinder E, for producing the connection through.

The smoke-chamber G is made with its sides inclose'd, as shown in fig. 1, and communicates with the exit-pipe I in the usual manner.

.This space is covered bya swing or. other cover, in which is a boiler-hole, for the insertion of a teakettle or boiler, and this boiler-hole, when not in use, is also covered by an ornamental vase or other cover.

H is a valve, covering the passage from the firechamber to the interior cylinder.

The operation is as follows;

When the valve H is closed, the draught passes upward through the series of tubes B, into chamber 0; thence down through jacket-space D, and thence up again through interior cylinder E,- to smoke-space G, whence .itfinally escapes through the smoke-pipe.

This produces an indirect draught, which economises the heat to the greatest degree, as it expends its force before reaching the exit.

A direct draught may be produced by simply .opening the valve H, thereby making a clear passage through interior cylinder E. v

I am aware that revertible fines are common in stoves, situated in the cyliuder,.around the firechamber itself. Such is not the equivalent of my arrangement, which is situated over the fire-space, and forms a distinct top to the stove.

I am aware also that in radiating drums an indirect passage is givento the draught, by means of tubes, passages, and jackets. 7 Such I do not claim.

A special feature of novelty in my invention in the construction of the above-described arrange ment is the inclosed. smoke-space G, of such shape as to form a convenient receptacle for a tea-kettle or boiler sitting over the opening in the cylinder E.

By this means, facility for boiling is produced,

chamber, so as to leave clear spaces at m, for the passage of the air.

'lheir tops are formed into angular flanges n n,

which cover the spaces or m, and prevent the en- 7 trance of ashes. I

'lheir bottoms do not quite extend to the bottom of the fire-space, but have an opening, 11, all around; for the free escape of such ashes as may collect inside.

The sides of the plates are filled with numerous fine perforations q q, for the distribution of the air properly to all parts ofthe fire.

The induction air enters on one side through an opening, 1', covered by a suitable register. A portion of this air enters directly through airpassage r to the fire-space, while the balance circulates through the spaces at m k, as before-described.

I am aware that closed plates, somewhat-resem bling in form the plates It, have before been used in stoves, to. form a downward or hot-air flue. Such I do not claim, as my plates are intended for a diiferent purpose, and, instead of being made. closed, are filled with perforations to feed the air in on all sides. .Such an arrangement would not answersimply for downward-draught flues.

The arrangement of the two perforated side plates, connected by anair-passage at the back, wherebythe whole is fed from one register, and the back space is left free=fur the insertion of icing-sticks of 2. The arrangement of the perforated plates K K wood, I belieie to be new. n v and connecting-passage k, combined together as de- What I claim, and desire to secure by Letters scribed, and operating in the manner and for the pur- Patent, is pose specified.
